Dear Paulo, I have a question: I can use iText to encrypt a pdf file (change permission). For example, I can make an pdf file not printable and set owner password, and later I can use the owner password to change the permission to make it printable again. But, the problem is if I make a pdf file not printable without setting owner password (password is null), later I cannot change it back (make it printable again) and always get error message: "reader was not opened with owner password", but I did not set owner password and there is no owner password. How do I solve this problem?
Thanks. Best Regards, Sam ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
